Maritime Geomatic SoftwareQPS QINSY

QINSy (Quality Integrated Navigation System) is a hydrographic data acquisition, navigation and processing software package. The suite of applications can be used for various types of surveys, ranging from simple single beam surveys up to complex offshore construction and engineering works.

QINSy is used for the integration of survey sensors, display of data during navigation, data processing and sharing of survey results.

More than 5000 QINSy licenses have been issued to over 700 companies in 71 countries worldwide and QINSy has a fast growing market share in the offshore oil and gas industry, dredging industry and port communities.Offered in a number of versions, QINSy is as equally well suited to standard positioning applications as it is suited to highly complex, multi-vessel and subsea vehicle, offshore construction operations.Furthermore, it can be customized with add-on modules like the MBES and SSS addons, plus Remote Display Control.

Multibeam

QINSy is extensively used worldwide for acquiring and processing multibeam data. The primary philosophy behind QINSy is to save time in processing, and the possible need for re-survey, by providing tools for real-time qualification of the raw data and on-the-fly correcting for offsets, motion, sound velocity refraction and height, to produce “final” xyz soundings as the survey proceeds. The multi-resolution and multi-layered “sounding grid” shown in the Navigation Display is populated with corrected soundings on-the-fly giving the surveyor a complete view of the project progress. Sounding grid data attributes like the “95% confidence level” and “hit count” provide real-time quality assurance of collected data. MBES Backscatter and/or sidescan imagery data can be simultaneously mosaicked to other layers of the sounding grid. By including a design terrain model or previous survey result, the surveyors can also see in real-time the difference between the most recent data and the other layers.

Dredging

Dredging vessels come in all shapes and sizes, and utilize several different methods of dredging, from suction to backhoe. Functionality in QINSy provides a full range of support for dredging vessels and excavators, from the smallest excavators to the largest cutter suction and trailing suction hopper dredgers (TSHD) in the world.

Bundle

A bundle is a large, pre-fabricated pipe enclosing multiple other pipes and cables of lesser diameter. Ultimately installed on the seabed, these bundles are assembled on land and can range over 7 kilometers in length. When launched, the entire bundle is towed out to the parking location somewhere offshore using tugs deployed on both sides of the bundle. During the tow-out, the bundle is completely submerged, floating a few meters below the sea surface. To mitigate sagging of any portion of the lengthy bundle, it is necessary to make the bundle buoyant over its entire length.

Laser

QINSy has long been known for producing fully corrected and geo-referenced multibeam point clouds in real-time. That ability led Mobile Laser Mapping System users to ask QPS if QINSy would generate similarly corrected and geo-referenced point clouds on-the-fly for laser systems interfaced to GNSS and INS sensors. While mobile platforms were already used in the land survey industry to collect the data, the idea of a REAL-TIME laser scanning system was to produce a DTM on-the-fly that is fully corrected for height, motion, position and timing as acquisition proceeds, consequently saving a great deal of post-processing time.

Side scan sonar

QINSy interfaces to most side scan sonar (SSS) systems commonly used in the hydrographic industry, whether they are hull-mounted, or towed behind the vessel housed in a fish. To position a towed fish, QINSy can use USBL positioning, cable counters and/or manual layback methods to compute fish track. Kalman filters of various strengths are available to smooth the track. If more than one method is employed to position the fish, QINSy will show and compare both positions.

Rockdumping

A large number of pipes and cables on the seabed need to be protected from anchors, trawlers and other risks. This is where specialty vessels enter the picture. Rock dumping vessels, or fall pipe vessels, can very precisely cover a submerged pipe or cable with rock. These types of operations are performed in waters up to a depth of 3000 meters below sea level. QINSy integrated navigation system software is regularly used worldwide on these specialty vessels to precisely position the vessel and the fall pipe ROV.

Rigmove

Drilling rigs are moved from one place to another on a regular basis. Locating the rig over the intended location in the specified orientation is a job QINSy handles well, as it provides all the necessary navigation and quality assurance tools to position the rig perfectly in the right spot.

Pipelaying

In many regions around the world, the seabed is laced with hundreds of pipe and power lines, mostly from platforms to shore and between platforms, but also from one country to another. These pipes and power lines are laid by a special type of vessel, called pipe-lay vessels or barges. Some are self-propelled by highly advanced dynamic positioning systems. Others move themselves by winching in and out on steel wires attached to large anchors deployed on, and recovered from the seabed by one or more anchor handling tugs. The costs of laying a pipe are so high that it must be placed correctly the first time of asking. Positioning of the vessel, tugs and pipe throughout the lay are of paramount importance.

Pipe Inspection

In most of the world, legislation requires that submerged oil and gas pipe lines, cables, and power lines, are inspected on a regular basis to ensure they have not been damaged or compromised by scouring of the seabed which can lead to excessively long free spans.
